Power (P) in "watts" in a circuit is the product in multiplying the current (I) in "amperes" and voltage (V) in "volts". 
  
                        P = I x V         ; I = P / V 

Substituting the given values,
                                    I = (25 W) / (230 V) = 0.1087 amperes

Therefore, the current is approximately 0.1087 A.
